Drake DENIED Postgame Access to Chicago Heat

Drake may be tight with LeBron James, but it wasn't enough to get him into the Miami Heat locker room last night.

Arena security totally denied Drake access to party with the Heat after they defeated the San Antonio Spurs, and unfortunately for Drake ... a WPTV camera guy saw it all go down.

The best part is when security tells the rapper, "This is media, pure media" -- and Drake replies, "I am media."

Btw, it didn't matter much ... Drake partied later that night after the shameful stunt with LeBron James and Dwyane Wade.
